I just aquired one of the new Savage BAS rifles. The whole thing is coated with a black power or oxide coating. The problem is the inside of the action along the bolt races is also coated. This is causing the bolt to bind slightly. I was thinking of putting a little lapping compound on the bolt to polish is up a bit and make it smoother. At the same time I don't want to cause any undue wear on the bolt lugs. Has anyone got an opinion on this?
